Standard grade Sapphire material is grown by Verneuil and Czochralski methods, whereas higher quality Sapphire is manufactured by the Kyropulus growth method. 

Our Sapphire Precision Windows are available in 1/2" and 1" diameters.​ Sapphire optical material has excellent thermal conductivity at low temperatures allowing single crystal Sapphire to be used in many diverse fields requiring thermal conductivity and heat radiation. The uncoated versions are designed for applications in the 150 nm - 4.5 μm range. AR-coated windows feature anti-reflective coatings designed for 1.65 µm - 3.0 µm (-D) or 2.0 µm - 5.0 µm (-E1) on both sides.
